Description
Technical field
The present invention relates to for detecting that exist to the environment around equipment, humidity, one or more parameters that acidity/basicity is relevant integrated-optic device.The present invention also comprises monitoring system for detecting this kind of parameter and method, uses this kind of system and method for the said equipment.
Background technology
In the field detecting the environment around given monitoring point, it is highly important that the parameter considering such as humidity and acidity/basicity and so on.
If there is the part of structure or the structure be made of metal in environment to be monitored, then it is also important to note that the evaluation performed the etch state of this kind of metallic member.
The load-bearing structure of solid structure (such as bridge or also have the underground structure of building, tunnel, railway, dam, Shui Di, Urban Underground railway) can be considered to for the significant application example of illustration purpose, but is not restrictive.Specifically, the structure (such as with the reinforced concrete that the concrete that Metallic rod is reinforced forms) of building materials can be considered.
In this context, be known for monitoring with the equipment of the different parameters of power or temperature correlation and system.Such as, the international patent application WO2012/084295 of applicant discloses for the equipment in solid structure internal monitoring mechanical stress and/or pressure and/or temperature, this equipment comprises the integrated detection module comprising at least one integrated sensor and interlock circuit device, and for externally with the calutron carrying out from outside communicating.In WO2012/084295, integrated detection module comprises the passivation layer of coating integrated sensor and interlock circuit device completely to guarantee robustness and long operation lifetime; But this feature makes this kind equipment can not detect humidity and/or acidity/basicity.The importance detecting the parameter of such as humidity and/or acidity/basicity and so on is vital with regard to meaningful and reliable monitoring.
The designer of structure to be monitored and maintenance technician need the water of evaluation due to existence and/or the progress of humidity deterioration.In fact, the phenomenon of this kind of deterioration can be caused varied.
With regard to concrete, this be combined by cement (be hydraulicity adhesive, its activation occurs due to the chemical reaction with water) be polymerized by the stone with different size the artificial stone material's (being called inert material (inert)) formed.Inert material has scope from the size of tens microns to tens microns.Cement granules has scope from the size of 1 to 50 μm, and their fill the space between the inert material that is present in whole porous and perviousness thing, and this space determines the thin pulp solidified.Concrete can have poriness in various degree and perviousness, depends on the size of its composition and inert material and cement granules, but can find poriness and the perviousness of specific degrees by some way.
Because this is true, humidity and/or other atmospheric agents and/or water (its in the solution can then comprise different chemical compounds) to be penetrated in concrete and can to cause some chemical/physical phenomenons, thus deteriorated concrete and be present in the metal of the bar (namely reinforcing steel or iron staff) in the concrete of reinforcing.Among the main cause of deterioration, following reason can be mentioned.
Carbonization is due to moisture, oxygen O
2with carbon dioxide CO
2to penetrating in cement.This kind of phenomenon does not relate to concrete robustness and reduces, but it is breakneck for reinforcing iron staff.Usually; in concrete; due to the lime formed by the aquation of cement; pH is alkaline (12-14) and therefore iron staff is passivated and is protected by this kind of alkaline environment by the formation of the passivation film of the ferriferous oxide that invests iron staff instead of penetrability, this prevent further oxidation.But, at the outermost layer (being also referred to as " concrete haunching ") of xoncrete structure by CO
2when penetrating, lime is destroyed and forms the calcium carbonate reducing pH, determines the environment of more and more acid, and starts the corrosion of iron when pH has the value of about 8 or 7.In addition, the rust formed by the oxidation of iron staff causes volume to increase, and determines the tractive force on concrete, and this can split and even cause concrete haunching layer to discharge due to tension loading; Therefore the iron staff of exposing surface is exposed to fast erosion, and this may cause the rapid degradation of structure and destroy its stability.
Sulphate corrosion occurs when the water permeated comprises sulfate, the calcium hydroxide of sulfate and cement, aluminate and silicate reaction, therefore form gypsum, entringite and thaumasite, therefore cause the expansion in concrete, split and discharge or be polymerized breaking of group.
Chloride corrosion is the chlorion owing to such as finding in the seawater.Chloride causes reinforcing the corrosion action on iron staff, and this action is removed above-mentioned ferriferous oxide passivation film and triggered further Quick Oxidation.In addition, sodium chloride can cause alkali-aggregate reaction when there is non-amorphous silicon dioxide, and this reaction forms alkaline silicate swelling in wet environment, and causes destructive splitting.Salt (i.e. sodium chloride) is therefore, it is possible to destroy the concrete of the reactive polymer reinforced iron staff and comprise such as non-amorphous silicon dioxide.Similar deterioration is caused by lime chloride, its cause reinforcing the corrosion of iron staff and its can further with concrete calcium hydroxide reaction, thus produce calcium oxychloride hydrate, this has destructive effect in result because volume increases.
It is only physical cause for deterioration that water due to the infiltration of water freezes circulation, and due to the formation of ice, result volume increases (about 9%), and this causes pressure repeatedly, and it can cause splitting and fragmentation in concrete.
According to the content illustrated above, urgent demand is apparent, and the wear reason namely by should not being subject to finding in solid structure to be monitored inside conversely as far as possible affects the demand of the existence of equipment monitor water and moisture and pH and the etch state of reinforcing iron staff.
In view of this, the humidity sensor comprising integrated circuit of principle of change of electric capacity of capacitor based on the outside being arranged in the passivation layer covering integrated circuit is known.
But, if this kind of known sensor is used to monitor building structure, then owing to being disposed in the corrosion of the metal electrode of the capacitor of the outside of passivation layer, the critical defect that is quite large and deterioration fast of sensor performance may occur, until it can't bear to use completely.
In addition, above-mentioned known humidity sensor can not monitoring parameter (such as, about pH's) acidity/basicity, and they can not perform directly and reliably evaluating of the corrosion stage reached about the metallic member be included in structure to be monitored.
With regard to parameter acidity/basicity, pH sensor is known, namely such as based on the concentration level wherein measuring this kind of metal oxide electrode of electric potential difference that creates at metal oxide electrode place and to be detected by different known possible methods the H+ ion in water: such as, when ISFET (ion-sensitive field effect transistor), there is the change of threshold voltage.The sensor of pH is also known, it is based on to have relative to pH be the electrode of inertia and be made into the structure of the electrode of pH sensitivity (in fact by pH sensitive layer, these structures have the capacitor as dielectric pH sensitive layer, and wherein the capacitance variations of this kind of capacitor is measured as the function of pH).
The known sensor of two types is all subject to the impact of the shortcoming mentioned relevant to the quick performance deterioration caused by the corrosion of the metallic member due to sensor when it is used in inside configuration to be monitored.
In addition, even if in this case, the known sensor being used for measuring pH can not measure humidity, can not provide the authentic communication in the corrosion stage reached about the metallic member be included in structure to be monitored.
Therefore, above-mentioned prior art solution fails to meet to provide to detect vital parameter (such as humidity and/or acidity and/or extent of corrosion, preferably more than one) and enough avoid mentioned worsening reason to be applicable to the demand of the sensor of (such as, when being embedded in building structure to be monitored) in wide operating conditions simultaneously.
The object of the invention is to conceive and by integrated electronics for the humidity of environment around himself of monitoring and equipment and/or the existence of water and/or the relevant at least one parameter of acidity/basicity, be therefore enhanced thus eliminate at least in part and meet the demand about the shortcoming described by prior art here.Specifically, the present invention also aims to conceive and be provided for detect the integrated electronics of at least parameter relevant with any above-mentioned phenomenon (existence of humidity and/or water and/or acidity/basicity) of the environment of equipment around himself.
In addition, the present invention also aims to conceive and be provided for the monitoring system of this kind of parameter and detect the method for this kind of parameter, it is by using the said equipment then can meeting the demand.

With reference to Fig. 1 and Fig. 6, now provide the further details of the embodiment of equipment 1.First it should be noted that in the equipment 1 in FIG, electrode 13 comprises by conductive material (such as, metal) the 3rd conductive members the 13, three conductive members 13 made is arranged to form the first capacitor C1 with the first corresponding electric capacity C1 to the first conductive members 11 and to form the second capacitor C2 with the second corresponding electric capacity C2 with the second conductive members 12.3rd conductive members 13 connects the first capacitor C1 and the second capacitor C2 by corresponding external impedance Z, make electromagnetic circuit 71 comprise the series connection of described first capacitor C1, external impedance Z and the second capacitor C2, and make the resulting impedance of electromagnetic circuit comprise the series connection of described first capacitor C1, external impedance Z and the second capacitor C2.
Therefore, it is possible to observe the equivalent circuit that the electromagnetic circuit 71 illustrating in figure 6 to draw is the equipment 1 presented in FIG, and it illustrates its operation.In addition, it should be noted that electromagnetic circuit 71 partly extends in equipment 1 inside relative to separate layer 14, and extend at its exterior section.
The measurement module 15 of equipment 1 is comprised potential source Vin (being instructed to relative to ground connection in figure 6) and such as can be detected the circuit arrangement of the resulting impedance of electromagnetic circuit 71 by the electromotive force Vout (being also instructed to relative to ground connection in figure 6) measured according to Vin.
Measurement module 15 can be configured to generate constant or variable voltage.

At this with reference to the lateral cross-sectional view demonstrated in Fig. 1, will notice that measurement module 15, first and second conductive members 11,12 (with other circuit optional) is integrated in a part for the functional circuit device 16 of the chip 10 at the upper integrated electronics 1 obtained of the substrate 17 (being such as silicon) of identical chips.
About the first and second conductive members, in the context of the embodiment of the equipment of Fig. 1, should be noted that they can have different configurations.Being described below about other possible configuration is herein more nonrestrictive implementation examples.
According to example, their each one or more sheet metals by having any shape are formed.
According to another example illustrated in figure 3 a, the first conductive members 11 and the second conductive members 12 are of similar shape; Their each conduction segmentations (such as, metal) by arranging with two comb-shaped are formed.More specifically, each conductive members comprise conduction segmentation parallel to each other 115 and laterally (such as, vertical) in the other conduction segmentation 116 of parallel segmentation, they are connected to central position by parallel segmentation.
The structure that crosses one another as above is advantageously applicable to when equipment 1 comprises other building blocks of function (such as the antenna) may determined the undesired stray current of conductive members.
Fig. 3 B illustrates other possible configuration of conductive members 11,12, and it provides other possible configuration of two conductive strip 11,12 extended along the circumference of two similar polygons respectively, and one in two similar polygons inner at another; A band in two bands corresponds to the first conductive members 11, and another corresponds to the second conductive members 12.
Notice in the embodiment shown in above, provide the first conductive members 11 and the second conductive members 12 is separated by inner insulation material 18, and be arranged to make generating this kind of distance of stray capacitance by this kind of inner insulation material.Therefore advantageously, when to its application electromotive force, the electric field generated thus is orthogonal about each conductive members (that is, for each capacitive character armature) substantially, and between the armature that the first and second conductive members are corresponding, there is not electric field line ideally.As having been noted that above, this kind of electric field can be constant or change in time; It is preferably variable.
Notice that the first conductive members 11 and the second conductive members 12 are both disposed in passivation layer 14 inner, and therefore they are protected for the wearing and tearing caused by outside agent.
In the context of the apparatus embodiments of Fig. 1, about the 3rd conductive members 13, should be noted that it can have different configurations.Describing below about other possible configuration is not herein more restrictive implementation examples.
3rd conductive members 13 comprises at least one part be made up of conductive material be disposed on separate layer, to form the geometric scheme of the multiple intermediate spaces (i.e. gap) such as comprising multiple band stretching, extension (i.e. band length) and comprise between band stretches; At least one Part I of the geometric scheme of band near the first conductive members 11, overlapping with it and by separate layer 14 spaced away; At least one Part II of the geometric scheme of band near the second conductive members 12, overlapping with it and by separate layer 14 spaced away.Partly overlapped by this kind of in the first and second conductive members 11,12 of the 3rd conductive members 13, and consider the separate layer 14 of insertion, define already mentioned first capacitor C1 and the second capacitor C2, it is the part of resulting impedance that will be measured.It should be noted that this kind of capacitor is included in the first armature of separate layer 14 inside and the second armature in its outside.
According to the implementation example presented in Figure 4 A, the 3rd conductive members 13 comprises multiple conduction segmentation 130 substantially parallel mutually.Advantageously, this kind of segmentation is mutual insulating, the invalid or undesired stray current of minimizing possibility in this kind of mode.
In another implementation example presented in figure 4b, the 3rd conductive members 13 comprises also the two groups of conductive strip 131,132 by the configuration that crosses one another that target is in this case minimum stray electric current.One group of band (with 131 instructions) is partly overlapping with the first conductive members 11, and another group band (with 132 instructions) is partly overlapping with the second conductive members 21.Another capacitor crossed one another is formed in the region that two groups of bands 131 and 132 extend between the described part overlapping with the first and second conductive members 11 and 12.
Notice in figures 4 a and 4b, the mutual location between the first and second conductive members 11,12 is illustrated in below separate layer 14, and the 3rd conductive members 13 is above separate layer 14.In order to illustration purpose, suppose that this kind of conductive layer 14 is transparent, make the first and second conductive members be visible.Therefore, separate layer 14 is sightless in figures 4 a and 4b, but should remember that it exists.
In figures 4 a and 4b, clearance space is indicated with Reference numeral 160.
According to another implementation example, the 3rd conductive members 13 comprises the conductive strip extended along the opening formed by segmentation parallel between two or closed polygon line.Specifically, as shown in Figure 5 A, conductive strip 133 extends along the description line overlapping with first and second conductive members 11 and 12 spirals of Fig. 3 B.
According to the another implementation variant shown in Fig. 5 B, the 3rd conductive members 13 comprises respectively along circumference two conductive strip 134,135 of two similar polygons (within another); The other structure 170 crossed one another can be there is between two conductive strip 134,135.
Notice that the equipment of the embodiment that basis describes before and variant is suitable for operating when time in the structure being embedded in solid material to be monitored, and it is configured to detect the humidity of this kind of solid material and/or the level of acidity/basicity, and detect the degree of the corrosion of the metal construction comprised in the inside of solid material to be monitored further.
According to important, nonrestrictive application example, structure to be monitored is reinforced concrete, and solid material to be monitored is concrete, and metal construction to be monitored is the Metallic rod of reinforced concrete, or reinforces iron staff.
In the application of this type, the above-mentioned clearance space 160 of the 3rd conductive members 13 is arranged and makes to be filled by solid material to be monitored after equipment 1 has been embedded in and it is in operating conditions.
In this kind of situation, the resulting impedance of electromagnetic circuit depends on the existence of humidity level and/or water and/or the acidity/alkalinity levels of solid material or the solid material comprised in the clearance space 160 of the 3rd conductive members 13 or absorbing material.The details of this kind of dependence is described in the description of detection method according to the present invention.
Illustrate the water droplet 90 of clearance space 160 inside between the band 130 of the 3rd conductive members 13 or the existence of moisture in the figure 7.In building materials, the existence of water and exogenous chemical material can reduce or more generally can change pH, thus those degradation phenomenas illustrated in such as determining at technical background description by corrosion phenomenon in conductive strip (such as, metal band).
Referring now to Fig. 8-10, describe the another embodiment according to equipment 1 of the present invention.This kind of embodiment corresponds to the embodiment (with different variants) that is described herein, except the first conductive members 11 and the second conductive members 12 are included in open in separate layer 14 and connection metal pad 111,121 that is that contact with the 3rd conductive members 13.Therefore, in this kind of situation, the resulting impedance of (schematically illustrating in the equivalent electrical circuit 72 of Figure 10) electromagnetic circuit comprises the external impedance of this kind of 3rd conductive members 13, and its first and second capacitors illustrated not included in preceding embodiment.
According to implementation variant illustrated in Fig. 9, the segmentation comprised by forming continuous open polygon line of the 3rd conductive members 13 extends, connects the conductive strip 136 (such as, metal band) of two pads 111,121.Segmentation is shown as parallel between two, but other configuration is possible certainly.
In this case, the external impedance Z of the 3rd conductive members 136 comprise active component caused by continuous conductive strip 136 and due between the segmentation parallel to each other of band by clearance space 160 in capacitive part caused by the capacity effect that creates of the material of deposition.
In all devices embodiment here mentioned, the conductive strip 130-136 forming the 3rd conductive members 13 is molded into by ink-jet the metal band that passivation layer 14 obtains.
This kind of band preferably by form structure to be monitored inner metal structures (such as, iron, steel or other) same metal make, under good approximation, therefore it stand similar corrosion.
Referring now to Figure 11 and 12, describe the another embodiment according to equipment 1 of the present invention.This kind of embodiment corresponds to illustrated those embodiments (comprising the variant that they are different), except following aspect: electrode assembly 13 comprise by contact with separate layer 14 or close to and the water that exists and/or moisture (such as, water droplet 90) the equivalent electrode assembly (13) that formed, to form the first equivalent condenser C1 with corresponding first equivalent capacity C1 to the first conductive members 11, and form the second equivalent condenser C2 with corresponding second equivalent capacity C2 to the second conductive members 12.This kind of equivalent electrode assembly serves as the equivalent external impedance of the value with corresponding equivalent external impedance.Therefore, electromagnetic circuit 73 comprises the series connection formed by the first equivalent condenser C1, equivalent external impedance Z and the second equivalent condenser C2 in this case; The resulting impedance of electromagnetic circuit 73 comprises the series connection of the first equivalent capacity C1, equivalent external impedance Z and the second equivalent capacity C2.
Notice once the 3rd conductive members etching of (being placed on passivation layer 14 outside), or exceed predeterminable level, the embodiment described in Figure 11 can correspond to the using state according to the equipment of other embodiment.Therefore, in addition in this kind of situation, the function that equipment 1 maintains, thus following information is provided: the generation of the very serious corrosion of outer metal element, and the generation of the therefore corrosion of the metal construction of building structure inside potentially; The existence of optional water and the pH of this kind of water.
This equiva lent impedance measured by measurement module 15 from very high value, basic be reduced to very low value (by causing of the water accumulated close to passivation layer 14) for infinitely (finding when there is no water and the 3rd conductive members of heavy corrosion is in non-operation condition) time moment observed, water departs from the line of electric force of electric field and in fact causes the connection between the area overlapping with the first conductive members 11 and the second conductive members 12 due to the conductivity properties of itself, thus forms corresponding equivalent condenser betwixt.
More specifically, the particulate 90 of water changes the line of force of electric field by electro-induction and forms equivalent external armature.Therefore, the existence of water is likely measured by the mode of the change of the electric capacity of this kind of equivalent condenser.Similarly, when there is acid or basic ion (electric charge of ion change equivalent condenser) near equivalent armature, use identical principle to measure pH change.
As in another embodiment, measurement module 15 is configured to application continuously or be preferably variable voltage.
If signal Vin is variable in time, then can measure the effective value (such as, root mean square) of output signal or the change of peak to peak value or Vout peak value, such as, to assess the capacitance variations of equiva lent impedance.Alternatively, if Vin is variable, such as sinusoidal, then equipment 1 can advantageously comprise resonant circuit LC (the introducing inductance of serial or parallel connection, do not illustrate in the drawings) so that the change of measuring the parameter (such as resonance frequency) of this kind of circuit changes can assess pH.In fact, the existence of the ion caused by pH have changed the electric charge of equivalent condenser and therefore have changed its electric capacity.
Referring now to Fig. 2, another embodiment according to equipment 1 of the present invention is described.This kind of embodiment corresponds to the embodiment (with different variants) shown in Fig. 1, also comprises a part for the absorbing material 19 (such as dielectric and/or polymerization) of mode absorbing moisture and/or water from ambient atmosphere environment of humidity and the acidity/basicity being suitable for indicating atmospheric environment except it.
Absorbing material 19 is arranged to the clearance space of filling the 3rd conductive members 13, and it covers the 3rd conductive members 13, comprises the 3rd conductive members 13 at least in part simultaneously.Do not describe according to implementation example, absorbing material 19 is arranged to and contacts with separate layer 14 and to surround the 3rd conductive members 13 completely, to form another electrode interbed except passivation separate layer 14.
In the embodiment of fig. 2, the resulting impedance of equivalent electric magnetic circuit depends on the humidity level of absorbing material 19 in the clearance space being comprised in the 3rd conductive members 13 and/or the existence of water and/or acidity/alkalinity levels.

Noticing can in laboratory or witness mark impedance under the condition of burying.Reference impedance provides the base value for this equipment, and such as it is measured under the condition similar to operating conditions, when namely similar at building materials to be monitored building materials is included between the clearance space of the 3rd conductive members.Normally, this kind of impedance is not having the humidity of water, given value (such as, very low), and for measured under the condition with reference to pH value (usually, pH=14, the pH expected in the concrete such as in starting condition).

According to the embodiment of the method, it uses the checkout equipment 1 according to any embodiment of equipment described before, and this equipment 1 can detect the pH value of the level of humidity and the existence of water and this kind of water and be present in the generation of state of the corrosion of metal in environment to be monitored.In this kind of situation, the step f of the method) comprise the following steps: the value based on the capacitive part of resulting impedance determines humidity level relative to the change of the initial calibration value being called as known humidity level; Whether appearance based on the relatively min/max peak value of resulting impedance is determined the existence of water or does not exist; If the existence of water detected, then based on the measurement of the relatively min/max peak value of resulting impedance value be called as known humidity level initial calibration value and/or with the relative min/max peak value measured at the peak value place previously detected compare the pH value determining the water existed; The generation of the state of seriously or completely corroding being present in the metal in environment to be monitored is determined when the value of the resulting impedance measured in the absence of water exceedes predetermined threshold value; If determined the state of seriously or completely corroding, then determine that the resulting impedance measured does not exceed described predetermined threshold value and reaches the water in the moment of relatively min/max peak value wherein.
For the measurement of each type, be necessary to understand qualitatively phenomenon and measure based on dependence.On the other hand, not necessarily express this kind of dependence by analyzing a situation, this is because likely from the viewpoint of operation by means of to making the resulting impedance of measurement and the initial token will being determined to advance to by the curve experiments that the associated change of often kind of parameter the parameter determined is relevant equipment.This kind of sign (being also referred to as initial calibration) causes the characterization data in the processor of the equipment that is stored in and/or in the processor of the external subsystems of monitoring system.
When considering the explanation of above report, measure institute based on qualitative phenomenon carry out comprehensively following.
The level of humidity is estimated by the change observing the resulting impedance measured; In fact, imaginary part, the capacitive part of especially this kind of resulting impedance depends on the humidity of the material in the clearance space being present in outer electrode device, and this humidity effect to be present between outer electrode device and correspondingly to affect the value of the electric capacity between the first and second conductive members; And affect the capacitive part of external impedance further.Basically, along with humidity level increases, the capacitive part of resulting impedance also increases, and therefore the value of this kind of resulting impedance declines.Normally, humidity change by " baseline " of the time trend of resulting impedance gradually and the change of " slowly " reflect.
Observe measurement resulting impedance rapid decrement thus cause detecting during relatively minimum peak value the existence of water.In fact, conceptually, the water of the thin layer in the clearance space of electrode assembly or the existence of a large amount of water cause sizable increase of the electric capacity related to, and it can reduce the real part (i.e. active component) of (conductive property due to water) external impedance further.
The value of the relative minimum peak of impedance that can be observed is relevant to pH level, therefore once be known with reference to peak value (such as corresponding to pH value=14), just allows it to evaluate.Therefore, likely relative to reference value evaluation or assessment relative pH value, this relative pH value is efficiently with fully for application considered here.
It is likely, however, that the relative peak-peak of impedance also can be relevant to the existence of humidity level, water, pH value.In fact, likely measurement module 15 with multiple different frequency or usually can perform impedance measurement in a frequency band, and make the overall behavior that can obtain impedance in this kind of frequency band, its middle impedance can have maximum or minimum peak.In other situation, can there is different chemical substances, this can cause the various actions of the impedance of measuring.
In the alternative of the method, possible: as observing substituting of peak value, to use suitable data processing algorithm to obtain interested parameter or its change about reference value.
Finally, become high especially in total resistance, when exceeding predefined threshold value in initial calibration step, determine the state of seriously or completely corroding of the metal of the electrode assembly of forming device.In fact, corrosion causes the interruption in the metal path of electrode assembly, and result increases the resistance (upper to unlimited) of external impedance.
In the method according to the invention, be intended to for give fixed structure (such as, reinforced concrete) the metal material of electrode assembly of equipment be selected to identical or closely similar with the material of the metallic member be present in structure (such as, reinforcing iron).Result, the determination of the etch state of electrode assembly provides the very reliable information of the state about corrosion, the state of this corrosion is almost identical with the state of the corrosion that the metallic member of structure experiences, the metallic member of this structure in identical structure by same material around and be exposed to the condition with the conditional likelihood of the electrode assembly of equipment.
